EScope2: Sharing Graph Data and Graph Options Between Domains

EScope2 introduces a new functionality with respect of EScope1 and it is now possible to define the colors of the waveform, the background and the title.

This application defines three panels. At the left side, when a database is open, the hierarchical structure is displayed and it is possible to navigate in the tree. When a node containing a valid signal is clicked, the corresponding waveform is displayed in the central panel. It is then possible to drag a crosshair over the displayed waveform, and the currenly selected (X, Y) pair values are printed in the upper panel.

The File Menu Bar option allows to:

• connect to a MDSplus server. The default server and port is localhost and 8000, i.e. a MDSplus data server running locally on port 8000 (the default configuration)
• open an experiment and shot. The default experiment and port is edam and 17615, respectively. They correspond to a database which is provided by the installer.
• exit from the application
  

The Graph Menu Bar option activates a pop-up panel which allows to associte a separate color to the graph title, the background and the plot line. The changes are applied when either Ok or Apply button is pressed.

To exercise this program the following steps are required:

1. If not already running, start a MDSplus data server. On windows, click on start->programs->MDSplus->MDSDataserver. On Linux, run script start_mdsip.
   
2. Change directory in  <source root>/escopes/escope2, where <source root> is the directory where you copied the source directory in the CD.
   
3. Include the current directory in your CLASSPATH environmante variable. On Windows this can be done by changing the CLASSPATH definition in Control Panel/System setting, or by the command
       set CLASSPATH=.;%CLASSPATH%
   On Linux (bash shell) this can be done by the command
      export CLASSPATH=.:$CLASSPATH
   
4. Compile  the java source files with the command
       javac *.java
   
5. Run the program with no arguments.
       java EScope2

When the edam database is open, valid signals are listed in the SIGNALS.PB subtree.
